Photocatalytic properties of titania nanoparticles obtained by laser ablation

Article

Abstract

The photocatalytic properties of titania (titanium dioxide) nanoparticles ablated by pulsed laser radiation are studied in this work. The influence of the subsequent annealing in a furnace at various temperatures on the properties of particles is studied. It is shown that the photocatalytic activity of particles decreases as the temperature of annealing rises. The degradation of the properties is associated with the growth in size of TiO2 nanoparticles and the decrease in surface defects in the process of thermal annealing.
